ABSTRACT
Objective To analyze the distribution and type characteristics of human papillomavirus (HPV) infection in women in Shiyan, Hubei region, so as to provide a basis for the prevention and treatment of HPV infection. Methods From January 2019 to December 2020, a sample of 3,180 women in XX region who had sexual intercourse experience were randomly selected, and their HPV genotypes were tested using flow-through hybridization, then the distribution characteristics and types of HPV infection in women of different ages were observed. Results Among of 3 180 patients, HPV infection was predominant in women aged 31-50 years , with 25.85% (822/3 180) aged 31-40 years and 22.08% (702/3,180) aged 41-50 years. HPV infection was the least prevalent in the ≤25 and >60 years age groups, with 428 cases and 289 cases respectively. HPV infection occurred in 1 310 out of 3 180 women , with a positive infection rate of 41.19% (1 310/3 180). HPV infection was most prevalent in the ≤25 years and ≥60 years age groups, accounting for 56.78% and 67.13% respectively. Single infection was the main infection type in all age groups, accounting for 76.03%. Twenty-one HPV genetic subtypes were detected in the subjects, out of a total of 1 918 strains of the virus. The main high-risk subtypes for single infection were HPV16, HPV52 and HPV58, accounting for 13.92%, 13.87% and 12.57% respectively, followed by HPV53 and HPV33, accounting for 7.61% and 5.58% respectively. The predominant low-risk subtypes for single infection were HPV11, HPV8 and HPV6, with accounting for 7.51%, 5.47% and 5.01% respectively. Conclusion HPV infection in women in Shiyan, Hubei region is predominantly in the ≤25 and ≥60 years age groups, and early clinical screening and preventive measures such as vaccination for high-risk HPV typing are of vital importance.
